Whats the cause of the large drop in CFM? Are the fans now tested whilst on a heatsink/case?

I'm responsible for pulling together the new methology article... but I've been swamped with other matters. There's no way to give you a nutshell summary. Please be patient, I hope to have that piece up in a couple days.

Larry is also working on new 120mm fan roundups. That should be done very soon as well.

Given I've just installed them today, I cannot answer with any sort of accuracy.

The numbers as reported in the reviews do matter for comparative purposes. Notice that the new methodology does not yield a 1:1 difference with any particular fan. The Noctuas apparently fare very poorly in the new testing set up, and that would have impacted my decision to buy them had I been able to have this information prior to buying.

In the end I'm mostly moaning about the near timing of it - I placed my order Friday, they arrived today, I read of the revised data last night. Missed it by a hair.

In the end it doesn't exactly matter what the CFM for a particular fan is - if it fits the application and moves as much air as I need it to and is quiet enough, then it is perfect. But those figures do serve a purpose when it comes to trying to determine which fans may best suit my needs in terms of air flow vs. rpm vs. noise.

I didn't mean to complain, by the way. While brand new to the forums I've been reading SPCR for a very long time and hold a deep appreciation for the work done here.

Hmm, the Noctuas really don't fare well in the airflow department, not after the updated results.

Still, when comparing the Noctua 800 to the Nexus, It looks like the Noctua still beats the Nexus in terms of cooling ability, given that they're on par for noise. Assuming, of course, that the Noctua's in more of a free-air environment, or on a HS with relatively normal fin spacing (Ninja). If airflow is the only change (the article isn't really clear), they're still better fans.

I'm considering replacing my Nexus fans, and even with the updated numbers from the article, the Noctua still looks more attractive. Except for price. They're $10 more expensive on average than the equivalent Nexus.

Of course, now the article has updated information on the Scythe fans, too. Some of them look real interesting, especially the Slipstream and S-Flex. Choices, choices.

It's so surprising that the 1900 RPM slipstream is more versatile and quiet capable than the 1600 RPM model that I still find it odd when I look at the data. For that purpose I find it nice to have it all on one page so I made this list:

Just take note and buy the better fan next time (fans don't last forever).

6 year warranty tho, almost forever

Imagine fuel costs rising every year. If you pay for S&H what is the true cost/value equation of shipping a fan back for warranty replacement?

Depending on what part of the world you are in compared to where you have to ship it to it might actually be cheaper to just buy a new fan for some people. Especially if the fan of choice is less than half the cost of the fan you bought the first time...

I suppose I'm about to find out. The Noctua NF-P12 I bought with two NF-S12s is misbehaving, giving off a terrible, loud warbling noise, no matter how fast or slowly it spins.

I'd likely be better off getting a Slipstream 1200 rather than pay to ship the Noctua anywhere.
